CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. application Ser. No.15/776,200, filed May 15, 2018; which is the US National Stage ofInternational Application No. PCT/IB2016/057013 filed Nov. 21, 2016,which claims the benefit of U.S. Provisional Application No. 62/258,648filed Nov. 23, 2015, the disclosures of all of which are incorporatedherein by this reference in their entireties.

BACKGROUND Technical Field

The present disclosure relates to lighting systems for vehicle windowshaving plastic glazing.

Technical Background

Vehicles such as sedans, coupes, sports utility vehicles, vans,hatchbacks, and the like typically include one or more of front, side,quarter and rear window structures. Moreover, such vehicles include oneor more light assemblies (e.g., a brake light, a puddle light). Theseparts and other parts may add to the cost and complexity of assembling avehicle.

In this regard, light assemblies in vehicles include a large number ofseparate components. For example, a typical vehicle may have severaldifferent types of lights, including, for example, parking lights, turnindicator lights, brake lights, and the like. Each of these lights maybe made from many parts. These parts add to the cost and complexity ofassembling a vehicle. Accordingly, as recognized in U.S. Pat. No.7,048,423 (“the '423 Patent”), it desirable to have a lighting assemblywith fewer parts. The '423 Patent discloses an integrated light assemblyincluding a plurality of lamps 210, 216 enclosed in a housing 202, whichmay serve as a lens for the lamps, and mounted on a substrate 204. Suchportions of a light assembly may add to the overall weight of a vehicle,and the overall complexity and cost of manufacturing and assembling avehicle. The above-noted problems with conventional light assemblies arecompounded by recent trends to increase the number of lights provided onvehicles. For example, lights provided for aesthetic purposes andutility purposes.

The present disclosure aims to solve these problems and other problemsin the prior art.

As described above the plastic glazing the 100 may be manufactured usinga molding process. In a particular aspect, a multi-shot injectiontechnique may be used to form the plastic glazing 100. In a first shot,a clear translucent material may be injected into a mold cavity having afirst volume to form the clear transparent portion 108. After the cleartransparent portion 108 is formed, the mold cavity may be adjusted to asecond volume and so on and so forth for receiving additional shots ofmaterial. In a second shot (or a third shot), a black or other coloredopaque material for the portion 110 may be injected to the mold cavitysuch that it binds with the clear translucent material. The twomaterials may bind together through melt bonding. That is, heat from theinjected opaque material may melt a surface of the already set cleartranslucent material such that a bond is formed between the twomaterials when they cool. During any one of the multi-shot injectionmolding processes the molded components 502, the cavity 212, the coloredportion 102, or any other aspect set forth in the disclosure may beformed thus reducing costs and complexity of the manufacturing process.During any one of the multi-shot injection molding processes the lightunit 214 or any other aspect set forth in the disclosure may be insertedand molded-in thus reducing costs and complexity of the manufacturingprocess.
